To all whom, t may 0011.667472,.-

Be it known that I, WILLIAM F. NIEBLING, a citizen of the United States, and a resident of Cincinnati, I-Iamilton county, State of Ohio, have invented a certain new and useful Water-Cooling Device; and I do declare the following to be a clear, full, and exact description of the invention, such as will enable others skilled in the art to which it appertains to` make and use the same, attention being called to the accompanying drawings, with the reference-numerals marked thereon, which form a part of this specification.

This invention relates to means for cooling water when the latter, after having been usedy in a certain manner and for certain purposes,

has become hot or warm and when it is nec-y essary to cool the same `to permit it to be used again. Such a condition arises, for instance,

in refrigerating plants, where water is usedy to cool the condensers and Where it is an 0bject to reuse this water,which otherwise would go to waste.

The cooling contemplated by my invention extends only as far as it is possible to be atlarly pointed out in the claims, is found a full `description of the invention, its operation,

parts, and construction, which latter is also illustrated in the accompanying drawings, inl

which- Figure l is a vertical elevation, partly in section, of my device. of one of the receiving-pans. Fig. 3 is a reduced side elevation of the water-motor. Fig. 4 is a sectional detail viewfof theftop bearing of the upright shaft. Fig. 5 is a diagrammatic top View, at reduced scale, of the device. v

The water to be cooled is discharged from a pipe 8 and received by the upper one of a series or stack of pans 9, preferably of circular shape and with perforated. bottoms, so that the water falls successively from one pan to the other. Downwardly4-that is, from one Fig. 2 is a top view!` L p an to another-these perforations vdecrease in size, but increase in' number, so that the discharging streams of Water decrease correspondingly iu size and increase in number. lThe exposure of the water to the cooler at- ;mosphere by the increasing number of thin streams or jets passing through the air is thereby also extended. and the desired result more readily obtained. The increasing numberof smaller holes requires a progressive enlargement downwardly of the size of the pans t0 prevent overflowing. They are supported one above the other and with a space between them in any suitable manner`-as,for instance, by brackets 11, projecting from anupright post 12. The exposure of the Water to the air, both as to time and space, is increased while flowing from one pan into the other by causing these latter to rotate, for which purpose upright 12 assumes also the function of a rotary 1shaft supported in suitable bearings at both its ends. At the lower end I provide for such purpose a flange 13, fitted into a box 1.4, with Aantifriction-balls 15 between them. At the upper end I use a recessed journal 16, rotating in a bearing 17, with antifriction-rollers 18 between the two. A nut 19 closes the space occupied by these rollers. Bearing 1,7 is sustain ed by suitable stays, braces, or, as shown, by so-called hog-chains 21, which connect to posts 22., Supporting-shaft 12 `may be r0- tated by any means, but I prefer such requiring no operating expenses, and whichl attain by providing a Water-motor driven by thewater discharged from the lowermost pan. For such purpose this water is collected and`concentrated in a tank 23, from which, through a pi'pe 24, it discharges upon the Wheel 25 of a suitable watermotor, as shown inFig. 3. Shaft 12 passes loosely through tank 23, the bottom of which is cut out thereat. To prevent leakage at this point, a sleeve or Wall surrounding shaft 12 is carried up from this opening in the bottom ofthe tank. (See dotted lines in Fig. 1.) The resulting rotation of wheel 25 is received by a shaft 2G, sup* ported in bearing 27, and transmitted to shaft 12 by aset of bevelgears 28. Byhaving two of these latter mounted on a sleeve 29l ength wise movable on shaft 2G, but forrotation connected thereto by the customary sl-iding key or spline on one fitting and moving in a IOO groove in the other, the direction of rotation of shaft 12 may be reversed. Such reversal is especially desirable where I also take advantage of the wind in this manner that the device is caused to rotate against the same, as shown in the diagram in Fig. 5. Since the action of the wind in this manner is available only for half of the device, its other half must be closed, which is best done by an angular partition 31, which should be movable to be adjustable to the veering of the wind. The cooled water discharged from pipe 24 after its 'action upon the water-motor is received by a tank 32, from which it discharges through an outlet 33 to be conveyed to the place of its reuse. It may go direct to such place, or, if necessary, be subjected first to additional cooling by artificial means.

34 is an additional bearing at the eXtreme lower end of shaft 12. Where the quantity of the water discharged from pipe 8 is not constant and decreases sometimes, so as not to completely spread over the discharging area of the pans, such areais reduced-that is, part of the openings therein are closed by ilaps 35, a sufficient number of which may be provided. When up, as shown, the full discharge a space between them and means to rotate` said shaft.
